Question What causes SymGetSymFromAddr64, GetLastError: 'Attempt to access invalid address.'?

Hello,

My app which worked until this weekend no longer works when built. It still works perfectly in the Editor.

* Title is now inaccurate because I discovered on another thread I could get a better stack trace by using the PDB option in the build

I've examined the Player.log in the TMP directory but it shows nothing that makes sense to me. The stack trace ends like the following, but the full file is attached.

It crashes when launched (straight after the 'Made in Unity' screen). The crash handler shows up briefly and disappears and the sound stutters for ~2 seconds before it closes.

Code (CSharp):

1.  
2. 0x00007FFEFE004983 (UnityPlayer) TerrainRenderer::ForceSplitParent
3. 0x00007FFEFE004994 (UnityPlayer) TerrainRenderer::ForceSplitParent

21. 0x00007FFFC762485B (ntdll) RtlUserThreadStart

Could anyone point me in the right direction to fix this? Everything in the scene and player settings looks good to me. I have already restarted the PC too. I've also cleared textures on the entire terrain and repainted them
